Description
The Backup Analog Power Supply Board (13.8V / 3A) is a reliable solution for powering 12V systems with integrated backup battery support. Designed as a PCB-mounted analog power supply, it provides stable regulated voltage while also featuring a dedicated output for charging backup batteries.
With an input voltage of 16V AC (via 130VA transformer), the unit ensures continuous operation and automatically switches to battery backup in case of AC failure. It also includes signaling outputs for AC power loss, low battery, and battery presence, making it a dependable choice for security, communication, and control systems requiring uninterrupted power.
